Abstract

Improved pneumatic suspension, of the type consisting of air bellows which ensure the assembly between the axles of the vehicle and frame or body of same, whereby the bellows are fed from an air reservoir via height regulating valves coupled with valves expelling the air, characterized in that the aforesaid pneumatic suspension is equipped with at least one angle measuring device (11) which is coupled with the aforesaid air expelling valves (9) so that from a definite lateral inclination angle of the vehicle, the air bellow or bellows (1-4) are freed from air at the high side of the vehicle.
